Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. An electronic device comprises: a display having a display state and a turn-off state; a processor having an operating state and a sleep state; and a touch panel configured to overlap the display, wherein the touch panel detects a first input, when the display is in the turn-off state, which is independent on the states of the processor and the display, and the first input is a touch input with a first input trace to be compared with a plurality of switching traces, and the touch panel triggers the processor and the display to perform a state switching according to the first input, wherein the first input comprises a first touch input, and when the processor is in the sleep state while the display is in the turn-off state and the touch panel has detected the first touch input, the processor switches from the sleep state to the operating state and the display switches from the turn-off state to the display state, wherein the first input further comprise a second touch input, the operating state comprise a first sub-operating state and a second sub-operating state, when the processor is in the sleep state while the display is in the turn-off state and the touch panel has detected the first touch input, the processor switches from the sleep state to the first sub-operating state and the display switches from the turn-off state to the display state so as to display a lock screen interface; and when the touch panel has detected the second touch input within a predetermined period of time, the processor switches from the first sub-operating state to the second sub-operating state and controls the display to display a corresponding operation interface, wherein the processor executes a command of a first command set in the first sub-operating state and executes a command of a second command set in the second sub-operating state, and the number of the commands in the first command set is smaller than that in the second command set, wherein when the electronic device is in the sleep state or in the power-off state, the display is in the turn-off state, wherein when an external power source connection is detected, the processor initializes the display, the touch panel and the charging controller of the electronic device, and wherein when the electronic device is in the sleep state, the processor operates at a frequency lower than the normal operating frequency.
An electronic device has a display (with on and off states), a processor (with active and sleep states), and a touch panel overlaid on the display. When the display is off, the touch panel detects a specific touch input (a "first input"). This input wakes the device. Specifically, when the processor is sleeping and the display is off, this "first input" turns on the processor and the display. The device also recognizes a "second touch input." Upon receiving the "first touch input", the device displays a lock screen ("first sub-operating state") and executes a reduced set of commands. A "second touch input" within a time limit unlocks the device ("second sub-operating state"), providing access to the full command set. In sleep or power-off, the display is off. Upon connecting to power, the processor initializes the display, touch panel, and charging. In sleep mode, the processor runs at a reduced frequency.
2. The electronic device according to claim 1 , further comprises: a trace determination coprocessor configured to determine whether the first input trace of the first touch input matches the first switching trace when the processor is in the sleep state while the processor is in the turn-off state and the touch panel has detected the first touch input; and when the trace determination coprocessor has determined that the first input trace matches the first switching trace, the processor switches from the sleep state to the operating state and the display switches from the turnoff state to the display state.
In the electronic device described previously, a separate trace determination coprocessor checks if the user's initial touch input (the "first input trace") matches a pre-defined unlock pattern ("first switching trace") while the device is asleep and the screen is off. If the touch pattern matches, the coprocessor signals the processor to wake up and turn on the display. If they do not match, the device remains asleep with the display off. This coprocessor handles only the trace comparisons of a touch input to specific switching traces.
3. The electronic device according claim 1 , further comprises: the trace determination coprocessor is configured to determine trace within a predetermined period of time when the touch panel has detected the second touch input; and when the trace determination coprocessor has determined that the second input trace matches the second switching trace, the processor switches from the first sub-operating state to the second sub-operating state, and the processor controls the display to display the corresponding operation interface.
The electronic device described previously uses a coprocessor that determines, within a specific time window, whether a second touch input's trace matches a second unlock pattern. If the "second input trace" matches the "second switching trace", the processor transitions from the lock screen sub-operating state to the fully unlocked operating state, displaying the corresponding unlocked user interface. This prevents accidental unlock or unintentional inputs.
4. The electronic device according to claim 1 , wherein the touch panel is configured on a first outer surface of the electronic device; the electronic device further comprises: a second panel configured to detect a second input on the first outer surface, which is independent on the states of the processor and the display, triggering the processor and the display to perform state switching according to the first input comprises: triggering the processor and the display to perform state switching according to the first input and the second input.
The electronic device described previously incorporates a second input mechanism on the same surface as the touch panel. This second input, along with the first touch input, triggers the device to wake up and change states. The device responds to both the touch input and the second input simultaneously, requiring both inputs for state transitions.
5. The electronic device according to claim 4 , wherein the second input is a press input, the second panel is a pressure sensor configured to detect the pressure applied onto the touch panel by the press input, which is independent on the states of the processor and the display, triggering the processor and the display to perform state switching according to the first input and the second input comprises: triggering the processor and the display to perform state switching according to the first input and the pressure applied onto the touch sensing unit by the press input.
In the electronic device with both touch and secondary input, the second input is a press detected by a pressure sensor under the touch panel. The device wakes up based on the combination of the touch input and the pressure applied to the touch panel. The pressure applied onto the touch panel by the press input is independent on the states of the processor and the display.
6. The electronic device according to claim 1 , further comprises a microprocessor configured to initialize the display, the touch panel and a charging controller of the electronic device when an external power source connection is detected.
The electronic device described previously includes a separate microprocessor that handles the initialization of the display, touch panel, and charging controller when an external power source is connected. This relieves the main processor from these tasks during the power-up process.
7. A state controlling method applied to an electronic device which comprises a display having a display state and a turn-off state, a processor having an operating state and a sleep state, and a touch panel configured to overlap the display, said state controlling method comprises: the touch panel detecting a first input, where the touch detects a first input when the display is in the turn-off state, where the touch panel detects a first input with a first input trace to be compared with a plurality of switching traces, which is independent on the states of the processor and the display, and the first input being a touch input; and triggering the processor and the display to perform state switching according to the first input, wherein the first input comprises a first touch input, triggering the processor and the display to perform state switching according to the first input comprises: the processor switching from the sleep state to the operating state and the display switching from the turn-off state to the display state when the processor is in the sleep state while the display is in the turn-off state and the touch panel has detected a first touch input, wherein the first input further comprise a second touch input, the operating state comprise a first sub-operating state and a second sub-operating state, the processor switching from the sleep state to the operating state and the display switching from the turn-off state to the display state when the processor is in the sleep state while the display is in the turn-off state and the first touch input has been detected comprises: the processor switching from the sleep state to the operating state and the display switching from the turn-off state to the display state so as to display the lock screen interface when the processor is in the sleep state while the display is in the turn-off state and the touch panel has detected the first touch input; and the processor switching from the first sub-operating state to the second sub-operating state and controlling the display to display a corresponding operation interface, when the touch panel has detected the second touch input within a predetermined period of time, wherein the processor executes a command of a first command set in the first sub-operating state and executes a command of a second command set in the second sub-operating state, and the number of the commands in the first command set is smaller than that in the second command set, wherein when the electronic device is in the sleep state or in the power-off state, the display is in the turn-off state, wherein when an external power source connection is detected, the processor initializes the display, the touch panel and a charging controller of the electronic device, and wherein when the electronic device is in the sleep state, the processor operates at a frequency lower than the normal operating frequency.
A method for controlling an electronic device with a display (on/off states), a processor (active/sleep states), and a touch panel involves detecting a touch input ("first input") on the touch panel when the display is off. The method involves comparing the trace of the touch input with stored switching traces to trigger a state change. Specifically, if the processor is sleeping and the display is off, the first touch input wakes up the processor and turns on the display. If a second touch input is detected within a time limit, the device transitions from a lock screen state ("first sub-operating state") to a fully unlocked state ("second sub-operating state"). Different command sets are executed in each state, with fewer commands available in the lock screen state. In sleep or power-off, the display is off. Upon connecting to power, the processor initializes the display, touch panel, and charging. In sleep mode, the processor runs at a reduced frequency.
8. The method according to claim 7 , further comprises: determining whether the first input trace of the first touch input matches a first switching trace when the processor is in the sleep state and the display is in the turn-off state and the touch panel has detected the first touch input, switching the processor from the sleep state to the operating state and switching the display from the turn-off state to the display state comprises: switching the processor from the sleep state to the operating state and switching the display from the turn-off state to the display state when it has been determined that the first input trace matches the first switching trace.
The state controlling method described previously involves verifying if the trace of the initial touch input matches a pre-defined unlock pattern while the device is asleep and the screen is off. Waking up the processor and turning on the display only occurs if this trace matches the pre-defined pattern. This adds a layer of security, preventing accidental activation.
9. The method according to claim 7 , wherein the processor switching from the first sub-operating state to the second sub-operating state and controlling the display to display a corresponding operation interface, when the touch panel has detected the second touch input within a predetermined period of time comprises: determining whether a second input trace of the second touch input matches a second switching trace when the touch panel has detected the second touch input within the predetermined period of time; and switching the processor from the first sub-operating state to the second sub-operating state and controlling the display to display the corresponding operation interface when it has been determined that the second input trace matches the second switching trace.
In the state controlling method described previously, unlocking the device requires matching the second touch input's trace to a second unlock pattern. The device only transitions to the unlocked state and displays the corresponding user interface if this trace matching is successful.
10. The method according to claim 7 , wherein the electronic device further comprises a microprocessor, when the electronic device is in the power-off state and an external power source connection is detected, said method further comprises: initializing the display, the touch and a charging controller of the electronic device by the microprocessor, where the processor ceases to operate when the electronic device is in the power-off state.
The state controlling method previously described utilizes a microprocessor. When the device is powered off and connected to power, this microprocessor initializes the display, touch panel, and charging controller, because the main processor is not operating in the power-off state.
11. The electronic device according to claim 1 , further comprises: a battery configured to enter a charging state, when the display is in the turn-off state and an external power source connection has been detected; a charging controller configured to acquire a charging progress information of the battery when the display is in the turn-off state and when the external power source connection has been detected; wherein, when the external power source connection has been detected and the touch panel has detected the first input, the display switches from the turn-off state to the display state so as to display the charging progress information of the battery.
The electronic device described previously includes a battery and charging controller. When the display is off and the device is plugged in, the battery starts charging, and the charging controller tracks the charging progress. If a touch input is detected while charging and the display is off, the display turns on to show the battery charging progress.
12. The method according to claim 7 , wherein the electronic device further comprises a battery and a charging controller configured to acquire a charging progress information of the battery, and triggering the processor and the display to perform state switching according to the first input comprises the display switching from the turn-off state to the display state so as to display the charging progress information of the battery when an external power source connection has been detected and the touch panel has detected the first input.
The state control method described previously for an electronic device with a battery and charging controller includes showing battery charging information. When an external power source is connected, and a touch input is detected, the display turns on specifically to show the battery charging progress.
